Evaluation of a triaxial operating vibration monitor applied to farm tractor

High levels of vibration coming from agricultural machinery can be transmitted to the operator’s body, requiring the need to create or enhance devices that allow the measurement of vibration levels. Design cost-effective equipment capable of monitoring the occupational vibration on machines and workstations allows one to extend the application of this equipment to monitor occupational conditions by detecting any inadequate conditions, thereby preserving the health of the worker. The present study was to evaluate the performance of a device for monitoring the operating vibration of an agricultural tractor, running during field operations. By means of tests, it was concluded that the device presented satisfactory performance, allowing the vibrational conditions of all three axes to be monitored from a distance, by means of spectral analysis, present at the point of installation on the agricultural tractor tested. The results shown were similar to those obtained in measurements taken with equivalent laboratory equipment.
